I agree that it sounds possible to unpot the plant and wash the ants away, but I have never had ants in my pots and so have no direct experience. In my Mexican garden, we have enormous underground colonies of leafcutter ants. This is like National Geographic, with trails of ants carrying parasols they have snicked out of my hibiscus and gardenias. A plantsman there suggested making a deep hole into a colony, perhaps by hammering a broom handle into it, pouring gasoline down the hole, tossing a match and running away as fast as possible. He says it leaves a crater and a bad smell but crimps the style of the ants. Don't try this in your bulb pots. I wonder why ants prefer your bulb pots to the ground. Is it the drainage? Most ants don't like to live in boggy ground. Do all the colonies appear similar, or do you have several species of ants? People pay good money to buy ant farms for their children.
